Performance Analysis of Bluetooth 5 for Smart Factory

Abstract

Background/Objectives:The RSSI performance of the Bluetooth 5 mesh node is measured according to the radio environment and by distance (1 to 20 meters).

Methods/Statistical analysis:GATT server signal strength is Power High, and the RSSI performance of the Bluetooth 5 mesh nodes is measured by distances of 1, 3, 5, 10, 15, 20 meters in a congested wireless environment. Likewise, the same experiment is carried out in a non-congested wireless environment. Another experimental environment involves a wall between Bluetooth 5 nodes where the radio signal is in a congestion.

Findings:According to the experiments in this paper, if the wireless environment (2.4GHz) is congested and the Line of Sight is guaranteed, the mesh nodes may be installed at every 5 meters approximately. On the other hand, if the wireless environment is not congested and the transmission speed is not important, the distance between the nodes is expected to increase from 15 meters to 20 meters depending on the field conditions in the Smart Factory. Additionally, the Bluetooth 5 nodes from 1 to 3 meters, as a result of the performance and by allowing a wall, permit communication.

Improvements/Applications: This paper shows the results of the experiment based on the performance analysis on the distance of mesh nodes in a congested environment and a non-congested one.
